Summary
G2-enriched fractions of Ehrlich ascites tumor cells (up to 80%–85% G2 cells) separated from anaerobically and aerobically cultured asynchronous populations by centrifugal elutriation revealed the same growth characteristics after recultivation under standard conditions: a significant proportion of cells with increased DNA (DNA content>4C) emerged. Interruption of DNA synthesis by deprivation of oxygen may account for polyploidisation (over-replication) of DNA but other mechanisms must be taken into consideration.
